1898—1902. No. 16.] FLOW. PLANTS AND FERNS OF N.-W.GREENLAND. 101 
withered when the specimens were collected, Aug. 11, 1899, were small 
and contracted, with few spikelets on short branches. The number of 
flowers in each spikelet does not exceed two, sometimes only one flower 
is developed. Here consequently we find the typical features of “G. 
vilfoidea”, but the vegetative parts call to mind rather the description 
of the var. arenaria, Fries (Mantissa, 2, p. 9). The specimens of Nat-. 
HorsT, which I saw in the Stockholm herbarium, represent the common 
arctic form of var. reptans. 
Occurrence. S. Ivsugigsok (NatHorst); Foulke Fjord, Reindeer 
Point (1479). 
Dupontia Fisheri, R. Br. 
D. Fisheri, Simmons, FI. Ellesm.; D. psilosantha, Ruprecut, Fl. 
Samojed. cisural. [D. psilosantha, Bessers, Amer. Nordpol-Exp.; Nat- 
Horst, Nachir.]. 
This grass has been identified by Asa Gray in Dr. BesseEts’ col- 
lection, and thus another locality added to its sporadic distribution in 
the arctic regions, [ am, however, inclined to think, that it may often 
be sterile and therefore may easily be overlooked. 
Occurrence. N. Hall Land (Bessexs). 
Distribution. To the statements included in my Fl. Ellesm., 
p. 161, must be added North-Eastern Greenland. 
Poa glauca, VaunL. 
P. glauca, Simmons, Fl. Ellesm. [P. glauca, Natuorst, N. W. 
Grénl.; P. caesia, Dickie, Not. fl. pl., in Increrietp, Summer Search]. 
I do not hesitate to pronounce this grass to be one of the most 
common plants of N. W. Greenland, notwithstanding that it is absent 
from the list of most collectors. This must, however, be because they 
have confounded it with others, or have totally overlooked it. Neither 
Hart nor Haves, for instance, have noted it for Foulke Fjord, where 
it is extremely common and appears both in the typical form and in the 
varieties elatior, (ANpERsS.) Lance, and tenuior, Simm. Of the latter I 
found a few individuals only, in fissures of the rock at Reindeer Point 
(1467); the former I found in abundance in large luxuriant tufts on the 
manured soil of Etah (235); the main form I found in various local- 
ities such as slopes, rookeries, etc.
